Vwith respect to these musical instruments as to combine their action toproduce certain harmonious effects.

One of the principal objects of this inven tion is to provide a playerpiano with an additional or. auxiliary bank of keys which are associatedWith organ or other instrumentsplaying mechanisms to manually operatethe latter in addition to and irrespective of the player piano, asdesired. Thus various harmonious results may be produced by the combinedaction ol? all of the player mechanisms and be controlled from oneinstrument,

Another object of this invention is to provide means whereby amaster-player instrument has complete control over the operation ofother player' instruments, such as organs, player-pianos, drums,cymbals, and all other instruments which are automatic in operation,thereby obtaining a harmonious combination resembling an orchestra.

ln the 1)resent embodiment of the invention the master instrument isdisclosed in the torni ot' a player piano arranged in electrical circuitwith an organ and a. second player piano, 1whereby all three instrumentsare controlled simultaneously from one instruinent.*the master. playerpiano. The master instrument is provided With means for controlling therendering of the accompaniment, or melody, by one or all of theinstrunienlis'in circuit, and is 'further provided 'with means,embodyinga separat?- banl; et keys, for manually operating theinstruments in circuit irrespective of the sellplayinp` mechanism of themaster instruu ment.

In the disclosed embodiment of the invention, the master piano controlsthe organ and second player piano in the following combinations.

(a) The master player pianov may automatically cause all three of theinstruments to play at the same time.

(o) The master player piano may automatically cause the organ alone toplay.

(c) The master player piano may automatically cause the second piano anditself to play in part, and cause the organ to sup- ,ply the remaining"part of the harmony.

(d) The master player piano may be man ually operated to play alone.

(e) The master player piano may be adjusted not only to play itself whenmanually operated but also to play at the same time the organ and thesecond player piano.

(f) The' master player piano may be manually operated to cause thesecond piano and the organ' to play in part only, such as certainchords, or melodies, While the master player piano alone produces theaccompaniment.

(g) rIhe master player piano may automatically cause the 4playing of theorgan and the second player piano in any of the above combinations, andat the same time may be manually operated, by the auxiliary bank ofkeys, 'to effect the playing of addi tional notes or chords to fill inor strengthen certain parts of the composition being erlecuted, asdesired.

With adjustments of this nature the va rious instruments may be soconnected in circuit that any oneof them may be made to play a soloWhile the remaining instruments play the accompaniment. In conjunctionwith this feature the invention provides for an indicator on the masterplayer piano to show which notes on the con trolled -instrurnents are inadjustment to respond to the operation of the master instrument.

A further object of this invention is to provide manually operable meanson the master piano for controlling the swell oi' the organindependently of the usual piano pedal control for the masterinstrument.

Other important objects and advantages of thisV invention will appearfrom the speciic disclosnireA in the following. speciication of oneembodiment of the invention, and illustrated in the accompanyingdrawings, in which:

The master player instrument is olisclose particularly in lig. 2 in. theform of s, player piano ci common construction provided with the usualtricher 13 over which passes the note sheet lll, the tracker 13 beingconnectecl by the air tubes or ducts 15 to the pneumatic operatingmechanism 16. The key hed. 17 ci the piano 10 cerries the usuel numberof keys 18, each being nron yiclerl with e stud or 'projection 19adjacent to its rear enel, which 'extentie upwardly enel beers againstthe lower one otl e pair oi? contacts 2O enti 21 mounted upon ssupporting strip l'abo've the key 18. lit is, oil-` course. understoodthat .a peli' of contacts 2G and Q1 is provitleci each key 18, thedrawings disclose the contacts normally open and to he cle-sed byoperation ci' the separato keys. The lower contacts 2J@ are all intlirect connection through wires with u source ot energy 23, in thepresent instance clisclosctl :is u buttery. Wires 24?:

connect the source of energy 23 to the upper 7c contacts 25 of :iiiuiiil'er ot' automatic switches controlled by the vpneuiiuitic pliiycriiicchsnism 16. The low. r contacts Q6 of these automatic .switches orcconnected by wires 2T to e like number oi. controlling 75 are normallyclosed end. are connected toso mainwires 32 from wiiich branch wires 33,and 33a leading respectively7 to the second player pieno gang switches3i and the organ switch Frein the opposite sides of the gang switches 34snol 3tlerc lestl 85 wires 3G and 37 leading respectively to the secondplayer piano anti, the organ.

Circuits are closed through the above (le scribed switches and wireswhen it is tlcsired to operate the mechanism of the master 9G playerpieno automatically. the automatic switches corresponding to the variousnotes of the instrument being operated by seperate piieuinatics 3o.

Should it be nesiretl to disconnect the pneumatic player mechanism itiancl operate the master instrument msnuelly by depressing the'varioiiskeys 18, the switch 39 is closed. fWlieii s key 18 is `tieni-esseci itsstutl 19 raises the corresponding lower Contact 2O 10c into engagementwith the upper contact 2.1, closing the circuit thi-o* h the wire l0leading into one sitle .of the corresponding switch 39.

The master player instrument is provided lie with en auxiliary orsecond. set of lteys Mountetl immediately beneath each ot the auxiliarykeys l2 is zi ont normally' open contacts 13 sntl li. Elie uppercontacts i3 are connected by the bronches so to the feed wire leadingfrom the batteryA while the lower contacts are connected by wires e6 tothe auxiliary liey switches 17. rllie opposite side ci. the key switch11? is in circuit with thewire 32 or 33 through a branchl 12u 48. lachlrey 4t2 is provided with e tlependingliigg or projection si)iior'inslly against the adjacent 'upper contee-t 43, enel serving todepress the seine sgsinst the regrw istering' contact when the lrey l2is @le 125 pressed. the instruments connecte@ to the nwitches 311 entihe operstec. menu lteys irrespective of 'the @lef instiinneiits theclosed through the switches 28 and 39, adl, mitting of the playing ofthe piano by the pneumatic mechanism or the manually 0perable keys.

Referring particularly to Figs. 2, 3 and l5, it will be noted that theivires 37 lead from the gang switches 35 to the corresponding magnets 49arranged in the vrind chest ol the organ ll, the magnets When energizedraising corresponding pallets exhausting air from the duct 50 openinginto the cross channel 51. The pipes 5:? in the swell boi; ol the organ.as shoivn in Fig. 3, are connected in the usual manner With the crosschannel 5l so as to effect the speaking of the pipes in accordance withthe operation of the sto is.

From the magnets 49 current passes through the ivire 53 to the battery23.

The organ in the present instance being relatively small is disclosed,particularly in Figs 3, 13 and l5 having but three stops, 54. and 56,each of which is operated by the separate magnets 57, 58 and 59. Themagnets 57, 58 and 59 are connected to the battery 23 through Wires 60connected to the return Wire 53. 'lWires (il, 62 and 63 lead from thestop magnets to the master player instrument, andare connected withcorresponding independent switches 64, 65 and 66 which are connected bybranches 24 to the battery These stops 55 and 56 may be independentlyopened by closing their respective switches 64. and 6G, as is desired by'the operator of the master player piano.

'From Fig it Will bc noted that all of the pipes are -located in theswell box G7. and that the swell box is provided with the usual louverblinds G8. From Figs. 8 and 9 it will he seen that the front G9 of theswell box is provided With a series of pneumatics 70 suitably coupled bylinks T1 independently to the lou'ver blinds C8 so as to open and closethe same. The pneumatics TO are connected through air ducts 72 to a windboi: 73 provided with a pair of opposed amlalteruat'cly opening andclosing pallets 74 niountcd upon a stem 75 carried on the movableportion of the pneumatic 7G communicating with the cross channel 77formed in the Walls of the wind box 73. The opposite end ot the crosschannel 77 opens into the duct or passage 78 extending through the Wallot theavind box 73. A valve or pallet 'Z9 is arranged midway ol the endsof the duct T8 so as to alternately close the interior of the Wind bof;to the duct 77 and to the atmosphere. it will be understood that theWind box 73 isprovided with a series of cross channels 77 correspondingin number to the pneumatics 70 and their operating mechanism, va magnet80 being located preferably Within the Wind box 73 over each pallet 79..iis will be seen from Fig. l5, one side of each of the magnets 80 isconnected by a wire 8l to the return wire 53 of the` battery 23, whilethe magnets 80 are connected at their opposite sides with acorresponding number or' leads-or wires 82 terminating in stud contacts83 disposed in segmental relation beneath the key bed 17 of the masterplayer piano. 'A knee-swell 84e is pivoted midway of its ends in asuitable manner against the underside of the key-bed 17. having itsouter end substantially flush with the outer edge of the key bed 17 for'operation to swing the same laterally, and

being provided upon its inner end ivith a segment 85 adapted to traversevthe contact studs 83 and close the circuit tl'iroigh as many of themagnets 8O asis desired. A, wire 86 leads from the pivotal support ofthe knee-swell Se to the battery to complete the circuit through themagnets 80.

Normally the contacts 29 and 3l of the tracker switches on the masterplayer piano are closed, and when it is desired to render inoperativecertain of the notes upon the dependent instrument, andjto not interferewith the operation of the same notes upon the master player piano, thesecontacts 29 and 31 are separated. To eifect the opening of theseswitches a pair ofslides 8? are held vertically 'for sliding movement ingrooved rests 88 attached to the upper side of the tracker i3. Theseslides 87 are pro videdwith beveled ends 89 adapted to move beneath theelongated extremities oi the upper contacts 3l, and to lift the samewhereby the slides 87 are .permitted to move clear across the trackerbeneath the contacts. The slides 8? are arranged for movement beneaththe contacts 3l. from opposite sides of the tracker 18, and are hingedat their outer ends upon the upper extremities ot rocker arms 90arranged in the trame of the master instrument 10, so as to swing towardand from each other to impart a like movement to the slides 87 to raisethe contacts consecutively from the opposite ends of the tracker, Forthe purpose ot' indicating to the opera-- tor the exact positions of theextremities of the slides 87, indicator arms 91 are employed, which arearranged in parallel fixed relation with the slides 87 and are ot thesame length so aslto move toward and from each other, and being advancedforwardly 'for movement in front of the note sheet 14. The indicatorarms 91 are provided with knobs 92 adapted to be grasped by the operau ltions to cut oil the desired notes.

@ther means 1s provided however for controlling vthe positions ot' theslides 87, the

saine comprising crank arins 93, upstanding from the lower ends of therocker aizns 90, adapted to swing concentric with the latter9 and beingconnected by links 94e to hand levers 95 hinged. upon the frame ot theinaster instrument in suitable position in front of the key-bed foroperation by the operator of the instrument.

ln conjunction with the pneumatic operating mechanism 16 for Diag/'ingthe master piano, ineans is provided 4for locking; the pneumatics 9Gagainst movement to actuate the hammer mechanisms in' order to edect theplayingr otthe organ or dependent player piano without sounding themaster player piano. This means as shown in Fig. 2 coinprises arms 9?"extending rearwardly i'oni the pneninatics S56, and in the path oi thehell crank levers 98 hinged upon. suitable rods for registration withthe pneumatics 96, having" one of their arms connected to a rod 99 forswinging their tree or opposite arms down against Athe arms 97 of thepneuinatics to prevent the latter from collapsine. The rod 99 isconnected to a hell hanger 100 to which is attached a pull rod 101having a .knob 1.02 at its outer end located beneath the lzeyphed 17adjacent to its outer edge.

The automatic playinga mechanism of the second player piano is otouhstanaily coin inon form, the dierence residing@ .in the applicationof a inagnetcontro j ,ed tracker opening mechanism in lieu otthefiisualnote sheetB the improved mechanism .comprising a channel hoard 103fitting over the traclrei 13 of the player piano mechanism, and having adepending portion 10e covering the openings of the tracker, and takingthe place of the note sheet. 'lihe channel hoard 103 is provided with aplurality ot cross channels 105 corresponding in nunihec to the channels in the tracker 13 and opening dii ctlif into the same. Each ot' thechannels 105 is provided with a port 106 opening into the atmosphere,and. normally closed by a valve'. '10?.

A. magnet 108 is arranged upon a suitahle hiacltet or other mounting 109immom diately over each one of the Valves 1079 and upon energization otthe it@ valve 197 is lifted from port to admit.

The spring contactsof these switches are 'electi'icalliv connected by blades which arecarried 'upon cross rods 11shaving outstanding arms 115 to which links116 are connected, turning the rodsl/i and. raising the blades 113 intoand out of engagement with the springs oi the switches. Tilting tablet-s117 are hinged across the 'forward side of the master player piano andhave inwardly ea',- 'tending arms 11S independently connected to therespec te links 116 of the rods 11st so as to indcpeiniently rock therods and operate the switches in separate groups.

From the foregoing description it. will he and seen that the operationof the improved playing apparatus will take place as folloven- Jihen theself-playing mechanism 16 is,

pnt into operation to play the master instrument, the push rod 101 isdrawn forwardly to throw the bell cfanl levers 99 out of the path of thearms 9T and adinit ot the uninterrupted n'xovcnient ci' the pneulnatics96. At this time the keys 18 are not opemtivev or at least theiroperation lis not counted upon for closing the circuit through thevarious switches, .hut the pnelunatics 38 operated to closethecorresponding contacts Q5 and 26 to close thc circuits through theswitches 28 and the tracker switches, which in 'turn are in circuit withthe dependent player piano through the gang switches 34 and the organthrough the gang switches 35. l/Vhen the two latter switches, and 35,are closed all three instruments are in operation. "With specialreference to Figs. 2, 11, 12 and l5, it will he noted that when theswitches 34 are closed the current passes from the battery 23 throughthe switches 34 and corresponding wires 36 leadingl to the independentplayer piano. The current passes .from the wires 36 through the magnets108 and returns to the battery 23 through the 'lfhe current in thecircuits thus described energize the correspending inagnets'iti whichraise the corresponding valves 107 and open the respective Thus, themagnets, 108 operate 'upon the tracker hoard 13 of the dependent pianosimultaneously with the striking otthe respective notes 'upon the masterinstrument.

From. Figs. 2, 3 and 1.5 it will he seen that when the switches areciosed the eurient passes from the hattery 23 through the switches 35and respective wires 87 to the magnets 49 in the orga-n 1.15 the currentreturning through the wire 53 tothe battery rthe magnets e9 being thusenergized.;

the correspondingq valves are opened andthe air in the cross channel 51is liberated, as hetetotore specn'icatl-y pointed out.

ases,

lt is thus noted that when the gang switches 35 are closed the organ isoperated simultaneously with the sounding of the various notes of themaster instrument.

The operator at the master instrument may control the organ stops byopening and closing the stopswitches 64, and 66 located on the masterinstrument, (Figs. 2 and 15) which open and close circuits through thestop magnets 57, 53 and 59, (Figs. 13 and 15) to actuate the stops inthe usual manner. Theflnee swell' (Figs. 2, l0 and 15) on the masterinstrument may also be controlled by the operator to throw the segment85 across any desired number of contact studs 83 to close the circuitsthrough the magnets 8O (Figs. 8 and 15) to open a corresponding numberof louyer blinds 68.

lt may thus be noted that the operator seated before' the masterinstrument has practically complete control over the playing andexpression of the various other instruments connected with the master'in-y strument.

if it is desired to silence the organ or dependent player piano, it isonly necessary to open e ther one or both sets of switches 3d and 36which control the circuits passing through the same.

`When it is desired to actuate the master player instrument manually andto render the automatic player mechanisms 16 inoper ative, the gangswitches 39 are closed to place the contacts 20 and 21 in the circuit sothat these contacts will be actuated upon the depression of theirrespective keys 18 to closethe corresponding circuits. l/Vhen one of thekeys 18 is depressed it closes the contacts 20 and 21, whereby currentpasses from the battery 23 through these Acontacts and through the wires4G to the switches 39, Current passes through the switches 39 andthroughl the wires L11 to the main wires 32 from w/hich the currentpasses through the branches 333and 33L to the switches 34e and 3:5.

lt is thus seen that from this arrangement Various combinations ina/y beeffected in playing certain of the instruments in part or in Whole,together with the master player piano, or without the same. 'l/Vhen itis desired that the master player piano play the accompaniment, and theorgan only,1or together with the dependent player piano, play the soloor melody, then the slides 87 are moved in from the opposite ends of thetracker 13 to open the tracker switches controlling the playing of thenotes indicated toward the edges et the note sheet 1st, which latterindicated notes may be arranged to correspond to theaccompaniment sothat the accompaniment will not be produced upon the organ or dependentpiano, and will be played only by the master instrument. The-slides-lare thus used to control the playing of the bass or accompaniment andthe treble or melody oi the dependent instruments. The slides 37 may beadjusted to hold open all of the circuits controlling the melody so thatthe dependent instruments play only the bass or accompaniment or theslides 87 may be adjusted to,hold open all ot the circuits controllingthe playing ot' the accompaniment s0 that the master instrument aloneplays the accompaniment and the dependent instruments harmonize with andstrengthen the melody of the master instrument. Thus the masterinstrument may be cut out wholly or in part from playing in thecombination.

The casing of the master player piano 10 is provided with a hinged panel119 in its front side, adapted to be swung into open position when it isdesired to gain access to the tilting tablets 117 to operate the several circuit switches, and to observe the in dicator mechanism inadjusting the slides 87. Any means other than the panel 119 may be'employed to eiiect these results, it it is ound more desirable.

The tilting tablets 117 are of substantial T-shape, having thecross-heads thereof :tacing outwardly and being operable by pressure ofthe lingers against the opposite ends of these heads to independentlyswing their arms about their common pivotal support to open and closethese switches.

It will be understood that this invention is not limited to the specificcombinations herein recited for blending the notes of the variousinstruments, but that the invention `comprehends all other combinati-onsand specific changes which may occur or be foundI practical in the useand installation of this musical apparatus, and which are within thescope of the appended claims.
